clutch/pressure plate

I need a second opinion and have searched the forum all over with no avail.

I need to know if a 10'' clutch will work with 10.4" pressure plate. If not will a 10.5" be to big.

any info would be greatly appreciative. Thanks.

Not sure why you can't get a match for the 10" clutch, but you don't want clutch material outside of the clamping surface of the pressure plate. So the 10.4"/10" would be the lesser of two evils assuming that material does not extend below the inside diameter of the pressure plate.

No where have i found a 10"sbc pressure plate its all 10.4" and up. If i can get away with the 10/10.4 then ill do that unless some can point me in the right direction that wont burn my wallet into my ass.

Getting into my conversion now, and have run into a glitch.

What pressure plate/clutch disc do I need?
The 944 has 23 splines and all the Chevy discs I see are 26 splines.
Does anyone have specific part numbers on what I need?

Texas performance lists a clutch disc for LS1 conversions, but I'm doing a SBC conversion.
Uses a 10.4 inch clutch not 11.0 inch LS

The Chrysler 1x23 works with the 944 splines. The 10.5" is as close as you will get to 10.4

You may want to contact Mcleod and ask them if they will put a 1x23 hub in a 10.4" disc.

Clutchnet.com will make a clutch disc for you with the 944 (Chrysler) splines in 10.4"

I have a 500 series Mcleod clutch in the car now and it is great.

I used clutches from Clutchnet before the conversion and they were excellent as well.

Whichever clutch you decided to use, do not use the solid hub versions. The drive shaft needs to have a spring centered clutch to absorb "shock" when the clutch is engaged.

You will be fine with a 10" disc in a 10.4 PP. It was very common for GM yo use a 9.5" disc with a 10.4 PP on the straight 6's in the 1960's. You do not want the disc to be outside of the diameter of the PP but inside if fine.

As for a 10,5 disc in a 10.4 PP, you would have .050" outside of the PP and I have never seen a disc that was oversize for the dia. but many PP's are slightly larger in diameter that their size. So you should be fine.

To show how common disc's with the 1" x 23 spline are, they are available in 6.25; 7.48"; 7.75"; 8.0"; 8.5"; 8.818"; 8.819"; 8.875"; 9"; 9.25"; 9.29"; 9.437"; 9.45"; 9.688"; 9.843"; 10"; 10.4" 10.5"; 11"; and 12" diameters.

While searching for a 9.25" disc for the 1uz swap, I ran across a 1x23 spline 257mm disc (10.1") from a 2001 Ford Ranger 4.0 V6
